Application filed May 31 1398. Serial No. 682,089. (No model.)

To aZZ whom it may concern: may be of any suitable length, but are pref Be it known that I, (JIOERO M. CUNLIFFE, a erably successively elongated the one beyond citizen of the United States, residing at Be the other from one side of the series of pipes troit, county of Wayne, State of Michigan, D to the opposite side of said series, while the 5 5 have invented a certain new and useful Impipes E are also preferably elongated one beprovement in Steam-Pipes for Heating Dryyon d the other from one side the series of Kilns; and I declare the following to be a full, pipes E to the other side of said series, as inclear, and exact description of the invention, dicated in Figs. 1 and 4.

This system and I carry out my invention as follows: arrangement of pipes, in connection with the 3 5 In the drawings, A represents any suitable headers, also provides for a drip-header to reinclosure for the kiln. ceive water of condensation at the bottom of B denotes a steam header or manifold of the whole series of pipes at the back end suitable proportions to supply a sufficient thereof.

This drip-header traction the pipes D exert a leverage on the O is shown in the drawings arranged subpipes E to turn them on the pivotal connectstautially at right angles to the longitudinal ing-pipes F, while said pipes F are also per direction of the steam-header B, although I mitted to turn in the unions Where the do not limit myself solely thereto. WVith the pipes D are made of considerable length, as 5 steam-header B is connected a suitable numindicated in the drawings, the expansion and her of steam'pipes D, so arranged that the air contraction will amount to considerable. At

Connected with the opposite extremiwise,while the pipes G will also expand lengthties of the pipes D are a series of transverselywise, and both being at right angles to the we 50 arranged pipes (indicated at E) connected pipes F and of substantially equal length the with the pipes D, respectively. The pipes D expansion of the two sets of pipes E and G will carry the pipes F in a corresponding direction without straining the pipes.

What I claim as my invention is' 1. In a system of steam-pipes, a series of pivotal pipes, a series of pipes united to each extremity of said pivotal pipes and arranged to swing thereupon in the expansion and contraction'of the pipes, and an additional series of pipes connected with vone of the'series of pipes united to the pivotal pipes and arranged to exert a leverage thereon under expansion and contraction, substantially as set forth.

2. In a system of steam-pipes, a series of pivotal pipes provided with right and left hand screw-threads at the extremities thereof, a series of pipes united to each extremity of said first-named pipes at substantially right angles thereto, and an additional series of pipes connected with one of the series of pipes united to the pivotal pipes and arranged to exerta leverage thereon under expansion and contraction, substantially as set forth.

3. Ina system of steam-pipes, the combination with a steam header or manifold, of a series of steam-pipes D connected therewith, a series of pipes E connected with the pipes D, respectively, at an angle thereto, a series of pipes F connected with the series of pipes E, respectively, a series of pipes G connected with the series of pipes F, respectively, and a drip-header connected with the series of pipes G, the series of pipes E arranged to swing on the pipes F, and the series of pipes D arranged to exert a leverage on the pipes E under expansion and contraction, substantially as set forth. 7

4. In a series of steam-pipes, the combination with a steam header or manifold, of a series of steam-pipes D connected therewith,

a series of pipes E connected with the pipes D, respectively, at an angle thereto, a series of pipes F connected with the series of pipes E, respectively, a series of pipes G connected with the series of pipes F, respectively, at an angle thereto, and a drip-header connected with the series of pipes G, the series of pipes F serving as pivots upon which the pipes E and G may swing in the expansion and contraction of the pipes, the series of pipes D arranged'to exert a leverage on the pipes E under expansion and contraction, substantially as set forth.

5.. In a system of steam-pipes, the combination with a steam header or manifold, of a series of steam-pipes D connected therewith, a series of pipes E connected with the pipes D, respectively, at an angle thereto, a series of pipes F- connected with the series of pipes E, respectively, a series of pipesG connected with the series of pipes F, respectively, at an angle thereto, and a drip-header connected with the series of pipes G, the series of pipes F havinga right and left hand threaded connection with the unions connecting the pipes E and G therewith, the series of pipes D arranged to exert a leverage on the pipes E under expansion and contraction, substantially as 'set forth.
